Part of the Milky Way, as seen through my beat-up old 50mm f/1.4 lens.
This was 25 "light" frames, plus 16 "darks" and a bunch of bias frames. All combined with DeepSkyStacker 3.3.2
Exposure data:

40-year-old 50mm manual-focus Nikkor-D lens at f/1.4 (wide open, so lots of coma)
Focused to infinity stop (no LiveView verification)
ISO 6,400
4 seconds per frame (1 min., 40 sec. total)
Mounted on a fixed tripod- no tracking, thus the relatively short 4 second exposures.

Here we go again. Re-processing because I'm bored with the flat grey skies.
This is a better version, much cleaner and more natural looking. Doesn't look quite as forced as the previous one.

One of the most fascinating regions of the sky, the region below the belt stars in Orion. The rather large nebula is the famous Orion Nebula, a region of new star formation 1,300 light-years away. The other region is just below Alnitak, the lowest of the belt stars. Here there is the Flame Nebula and the famous Horsehead Nebula, a faint hydrogen-alpha area with a dust cloud in the shape of a horse's head. It's hard to see here, but in a longer focal length lens it should look well defined.
The oldest known cluster in our galaxy at 12 billion years old.
This image is made from 12x180 second exposures @ISO 800 plus 10 darks, 10 bias and 10 flat frames. I also used a 42 second exposure to bring out some of the detail in the very dense and bright centre of the cluster.
Phd2 guiding was used to guide my field flattened ED80 using a ZWOASI120MC camera (0.2 second exposures) attached to a SW 80T guide scope.
Capture camera was an unmodified canon EOS40D DSLR controlled by my home made camera trigger allowing mirror flip then Stacked using deepSkyStacker.

M51 - E' una delle più belle galassie del cielo boreale, situata nella costellazione dei Cani da Caccia. Avevo già ripreso questa galassia (dovremmo in realtà parlare di una coppia di galassie interagenti) anni fa con scarsi risultati.
A dire il vero non sono soddisfatto da questa aleborazione. Purtroppo le immagini raw di provenienza non erano delle migliori: ho effettuato la ripresa da un luogo parzialmente inquinato con un newton da ben 42cm, disturbato anche da alcune luci che hanno creato un fastidioso gradiente (rimosso con PixInsight): sono quindi stato costretto a fare pose molto corte (sfruttando l'apertura ed il diametro dello strumento).
Dati tecnici: 5x90"@800iso + 4x30"@1600iso + 9x60"@1600iso + 5x90"@1600iso per un totale di 26 minuti di ripresa (con sottrazione del dark).
Da notare che l'immagine in questione è stata ripresa il 28 aprile del 2008.

-------------------------------------
This is one of the most incredible galaxies in northern sky, located in Canes Venatici constellation (Hunting Dogs). I already imaged this galaxy (we should talk about an interacting pair of galaxies, to be precise) long time ago with poor results and with weaker experience in astroimaging.
I'm not very satisfied with this image though. Unluckily, raw images weren't good enough: i made the exposures from a partially light-polluted sky with a 42cm (about 17inches) newtonian reflector, also disturbed by some lights wich created an annoying background gradient (removed with PixInsight): so i've been compelled to make short exposures taking advantage of aperture and diameter of that telescope.
Technical datas: 5x90"@800iso + 4x30"@1600iso + 9x60"@1600iso + 5x90"@1600iso , for a sum of 26minutes equivalent exposure (subtracted darks too).
Besides, this image was captured on april 28th of 2008 (i preferred waiting for better wnowledges in post processing).

A couple days ago, I took some more shots to extend the total exposition time for this photo from 16 minutes to 38 minutes.
It certainly helped pull out more of the Running Man and the faint loop opposite M43 (better transparency the second time didn't hurt either). But I've had trouble processing it -- I don't know where those horizontal red lines are coming from. They're vertical with respect to the camera sensor, and I don't usually see pattern noise like that--it's not visible in the individual light frames (but to be fair, neither is a lot of the faint detail I managed to pull out of the stack).

The Rosette nebula imaged at our local Stargazing Live event in Ipswich on the evening of monday Jan 16th - a slightly better processed version than the last :-)
Whilst the 300 (yes, 300!) people were all queing up to look through some of the scopes set up I was showing them images taken on my modest imaging rig via my laptop. In the mean time the rig was snapping away at the Rosette nebula.
This is a total of 23 X 6 minute exposures with matching darks and flats applied. The full details are as follows:

The images comprising this were taken through drifting, thin cloud - of course, while setting up and locating the (dim) subject, the sky had been perfectly clear! The stars are not as sharp as I'd like, due to various factors. Still, I was pleased with the result, given the conditions.

Hard to believe that this is the same data as the previous iteration, and it is a little less embarrassing! I put this back through DSS (multiple times) using the same settings, but in this case I reset all white balance settings (as I use a modded DSLR) and also used RGB background calibration instead of Per Channel. Even the pelican has put in a tenuous appearance, and the detail at the top of the image is vastly improved. A little bit clipped, but I'm not going to lose any sleep over that. :)
It all takes time, but in this case I think it was worth it :)

Photo info: several shots stacked with DSS (DeepSkyStacker - deepskystacker.free.fr/english/index.html only to increase the Signal to Noise Ratio (SNR).

Cropped quite a bit.
Oct. 2 update: Removed some of the light pollution gradient.
Mar. 7 update: Star reduction.
The comet, currently in Andromeda, was easily visible via 7 x 50 binoculars. However I couldn't image through the 'scope, as the comet is to the West and my view is blocked, so I just used a short telephoto lens on a star tracker, and cropped the result a little. The comet’s tail can be seen faintly in the photo, pointing to the 2 o’clock position. The slight gap in the star trails is due to the sequence of frames being broken by passing cloud.
19 x 30-sec exposures at f/4 and ISO 3200 with an EOS 600D and Zeiss Jena 135mm f/3.5 lens, on a Vixen Polarie star tracker; frames stacked on the comet (hence the slightly trailed stars) in DeepSkyStacker, with curves adjustment and further noise reduction in post-processing.

Canon EF 50mm lens (MK I), at f/2.8, ISO 800, three hand-tracked exposures (total exposure time 5m 15s), combined in DeepSkyStacker and processed in Photoshop.
I would have gone deeper, but the clouds rolled in. Still, you can see the beginnings of the dust lanes on the large version, and the two satellite galaxies (annotated).
New set of images for this one. My autoguiding is getting better and better after many frustrating hours tuning the mount. Very happy with the star detail on this one.
